WINDING-KEY FOR GUITARS.

SPECIFICATION forming part of Letters Patent No.'510,375, dated December5, 1893. Application filed March 3, 1893- Serial No. 4645 (N0 modem Toall whom it may concern.-

Be it known that 1, JOHN AYUsO, of Brooklyn, in the county of Kings andState of New York, have invented a new and Improved VVinding-Kcy forGuitars, Mandolins, and like Musical Instruments, of which the followingis a full, clear, and exact description.

My invention relates to a winding key for guitars, mandolins, banjos,and like stringed instruments, and it has for its object to provide asupplementary key adapted to be used in connection with what is known asscrew keys, whereby the latter keys may be much more rapidly andconveniently manipulated than by applying the fingers directly to them,and whereby also instead of the half turn only which can be given to thescrew by the. fingers at one manipulation thereof, the said screw can begiven a complete revolution at each manipulation.

Another feature of the invention consists in so constructing thesupplemental key that it will be entirely independent of the ;screwkeys, and whereby one supplemental screw key winder may be used inconnection with the entire set of screw keys.

The invention consists in the novel con struction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure 1 is a side elevation of a set of screw keys showing thesupplemental key applied to one of them, the supplemental k'ey being invertical longitudinal section. Fig. 2 is a detail perspective view ofthe supplemental key; and Fig. 3 is a transverse section through thesupplemental key and through one of the handles of the screw key.

The group of screw keys A, shown in Fig. 1, are of the ordinary type,each key embracing a worm shaft 10,provided at its outer end with ahandle 11 and a worm wheel 12 meshing with the worm shaft. The handles11, are

of essentially circular contour, but their opposite side faces aresomewhat convexed, the handles being therefore thicker at the centerthan at any other portion.

The supplemental key B, maybe made of any suitable or approved material;for example, metal, celluloid, bone, rubber or hard wood may be used,and the supplemental key comprises a body 13, having a socket14,produced in one end the cross sectional shape of the socketcorresponding to the cross sectional shape of the handle of the screwkey; therefore, the socket is somewhat oblong and its side walls areconcaved. The socket is made just deep enough, preferably, to receivethe entire handle of the screw key, or the major portion of the handle,and the two fit in such manner that while the screw key may bemanipulated by turning the auxiliary key one may be readily disconnectedfrom the other. In addition to the body 13 provided with the socket 1 1,the auxiliary key comprises a handle section 15, which may be integralwith or attached to the body, and is preferably located at the endopposite that in which the socket is placed.

It will beobserved that when the auxiliary key B, is employed, one keymay be used for turning any of the screw keys upon the instrument; andit is likewise evident that a screw key may be manipulated much morerapid y and conveniently when the auxiliary key is applied to it than ispossible to do by hand, thereby providing for the quick winding of thelengthy end of the string upon a key. Furthermore, when screw keys aremanipulated by hand the keys can be given but one-half a revolution orone-half a turn at one grip, but when the auxiliary key is employed thesame force applied to the auxiliary key that has heretofore beenemployed upon the ordinary winding key will turn the latter a completerevolution.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. As an improved article of manufacture, a windingkey for the screw keys of guitars, mandolins and similar instruments,the said auxiliary key comprising a body having a socket formed in oneend of corresponding cross sectional shape to the cross sectional shapeof the head or handle of the screw key, and a handle section secured tothe body and forming a longitudinal extension thereof, as and for thepurpose set forth.

2. An auxiliary winding key for the screw keys of guitars, lnandolinsand like stringed instruments, the same comprising a body sectionprovided with a socket in one end corresponding in cross sectional shapeto the cross sectional shape of the head or handle of the screw key, anda handle projected from the opposite end of the body in longitudinalalignment therewith, the said handle being I0 practicallystraight, asand for the purpose set forth.

3. The combination, with the head or handle of a screw key for guitars,mandolins and like instruments, of an auxiliary key comprising a bodyprovided with a socket corresponding' in cross sectional shape to thecross sectional shape of the said head or handle, the socket looselyreceiving the head or handle, and a handle section secured to the bodysection of the said auxiliary key in longitudinal alignment therewith,as and for the purpose set forth.
